Effect of anti-reflux suture on gastroesophageal reflux symptoms after one anastomosis gastric bypass: a randomized controlled trial.

PURPOSE: Gastroesophageal reflux disease (GERD) is an issue after one anastomosis gastric bypass (OAGB) and modification of OAGB with adding an anti-reflux system may decrease the incidence of postoperative GERD. This study aimed to compare the efficacy of the anti-reflux mechanism to treat preoperative GERD and prevent de novo GERD. METHODS: A prospective randomized clinical trial study was conducted on patients with a body mass index of 40 and more from August 2020 to February 2022. Patients undergoing one anastomosis gastric bypass with and without anti-reflux sutures (groups A and B, respectively). These patients had follow-ups for one year after the surgery. GERD symptoms were assessed in all the patients using the GERD symptom questionnaire. RESULTS: The mean age was 39.5 ± 9.8 years and 40.7 ± 10.2 years in groups A and B respectively. GERD symptoms remission occurred in 76.5% and 68.4% of patients in groups A and B, respectively. The incidence of de novo GERD symptoms was lower in group A, compared to group B (6.2% and 16.1% in groups A and B respectively), without any statistically significant difference (p-value: 0.239). CONCLUSION: GERD symptoms and de novo GERD after OAGB seems to be under-reported after OAGB. This study suggests that applying an anti-reflux suture can decrease de novo GERD symptoms.

The predictive relationship between early and long-term weight loss outcomes after one anastomosis gastric bypass.

BACKGROUND: Weight loss failure after bariatric surgery imposes great stress on patients and surgeons and great costs on healthcare systems. The literature review shows that weight loss failure is the most common cause of redo bariatric surgery. Therefore, identifying the predictors of weight loss failure in patients in the early stages can help bariatric surgeons. The present study aims to determine the association between primary weight loss and long-term weight loss outcomes. METHODS: This retrospective cohort study was conducted on 329 patients undergoing OAGB who were followed for 60 months. For the prediction of short-term (24 months) and long-term (60 months) successful weight loss and weight regain, we used %TWL and BMI at any regular follow-ups. RESULTS: In preoperative indices, age, sex, DLP, hypothyroidism, and HTN were not significant to predict successful short-term and long-term weight loss but %TWL at 12 months is a significant predictor of successful weight loss in short-term and long-term follow up. In the prediction of weight regain, preoperative indices (except BMI) were not significant but 12-month %TWL was a significant predictor. CONCLUSIONS: This index can help surgeons find these patients early and provide helpful instructions to manage their issues more promptly to reach better weight loss outcomes.

Efficacy of intra-ovarian injection of autologous platelet-rich plasma in women with poor responders: a systematic review and meta-analysis.

CONTEXT: The effect of platelet-rich plasma (PRP) on ovarian reserve markers in poor ovarian response (POR) is challenging. AIM: This systematic review and meta-analysis was, therefore, designed to evaluate the effectiveness of intra-ovarian injection of autologous PRP on improving ovarian reserve markers and assisted reproductive technology (ART) outcomes in infertile women with POR. METHODS: A systematic search was conducted for the efficacy of intra-ovarian injection of autologous PRP on the improvement of ovarian reserve markers and ART outcomes in infertile women with POR. The methodological quality of the included studies was checked and eligible studies were included in the meta-analysis to find pooled results. Keywords were primary ovarian insufficiency, premature menopause, poor responder, poor ovarian response, diminished/decreased ovarian reserve, platelet-rich plasma, and intra-ovarian or a combination of them. The effect of PRP on fertility indices was evaluated using the standardized mean difference (SMD). The analysis was performed through STATA version 13. KEY RESULTS: 13 studies containing 1289 patients were included. Mean age, body mass index (BMI) and duration of infertility was 37.63 ± 2.66 years, 24 ± 1.23 kg/m2 and 4.79 ± 1.64 years, respectively. Most of the studies measured the outcomes 2-3/3 months after intra-ovarian injection of autologous PRP. The antral follicular count (AFC) after treatment by PRP is higher with an SMD of 0.95 compared to before treatment. The day 3 follicle-stimulating hormone (FSH) after treatment by PRP is lower with an SMD of - 0.25 compared to before treatment. The day 3 estradiol (E2) after treatment by PRP is higher with an SMD of 0.17 compared to before treatment. The anti-Mullerian hormone (AMH) after treatment by PRP is higher with an SMD of 0.44 compared to before treatment. The total oocytes number after treatment by PRP is higher with an SMD of 0.73 compared to before treatment. The number of MII oocytes after treatment by PRP is higher with an SMD of 0.63 compared to before treatment. The number of cleavage-stage embryos after treatment by PRP is higher with an SMD of 1.31 compared to before treatment. The number of day 5 embryo after treatment by PRP is higher with an SMD of 1.28 compared to before treatment. Pooled estimation of a meta-analysis of prevalence studies reported a prevalence of 22% for clinical pregnancy, 5% for spontaneous pregnancy and 21% for ongoing pregnancy following PRP therapy. CONCLUSION: Intra-ovarian injection of PRP improved ovarian reserve markers with increasing AFC, serum level of AMH and day 3 E2 and decreasing serum level of day 3 FSH. In addition, this treatment improved ART outcomes through the increasing of number total oocytes, number of MII oocytes, number of cleavage-stage embryos and number of day 5 embryos in POR women. IMPLICATIONS: Although treatment of POR women remains challenging, the use of intra-ovarian injection of autologous PRP in POR patients prior to IVF/ICSI cycles is a sign of new hope for increasing the success of IVF/ICSI. However, further well-organized, randomized controlled trials should be conducted to substantiate this result and recommend intra-ovarian injection of PRP as part of routine treatment in women with POR.

Metabolic and bariatric surgery in patients with class I obesity; a two-year follow-up.

BACKGROUND: Patients with class I obesity may need metabolic and bariatric surgery (MBS) in the presence of obesity-associated medical problems, but MBS in this class of obesity is under debate. This study aimed to investigate the efficacy and safety of MBS in patients with class I obesity. METHODS AND MATERIALS: This study was a historical cohort carried out on 112 patients with class I obesity with body mass index (BMI) of 30-35 kg/m2 with a 24-month follow-up underwent MBS at Rasoul-e-Akram Hospital. The required data were extracted through the Iran National Obesity Surgery Database. The data required for the study consisted of demographic information such as age, gender, and obesity-associated medical problems like type-2 diabetes mellitus (T2DM), hypertension, obstructive sleep apnea, and dyslipidemia before surgery, 6, 12, and 24 months after surgery. RESULTS: Mean age of the patients was 38.10 ± 10.04 years; mean BMI was 32.96 ± 1.35 kg/m2 and 83.9% (n = 94) of patients were female. Out of 18 patients with T2DM, 11 patients (61.11%) had complete remission and seven patients (38.88%) had partial remission. Obstructive sleep apnea, hypertension, dyslipidemia, and gastroesophageal reflux disease were observed in 18 (16.07%), 23 (20.53%), 43 (38.39%), and 13 patients (11.60%) before surgery and resolved at 24-month follow-up. Post-operative complications during the 24-month follow-up were checked to assess safety and there were no De novo gastroesophageal reflux disease, intolerance, leakage, pulmonary thromboembolism, deep vein thrombosis, incisional hernia, hypoalbuminemia (Albumin < 3.5 g/dl), excessive weight loss (BMI < 18.5 kg/m2) at any time during 24-months follow-ups and mortality. Early complications occurred as splenic injury in one case (0.89%), wound infection in one patient (0.89%), and extra-luminal bleeding in 10 (8.92%) after surgery, without any mortality. CONCLUSION: MBS is safe and effective in class I obesity and can be considered in selected patients with obesity-associated medical problems.

Severity of post-Roux-en-Y gastric bypass dumping syndrome and weight loss outcomes: is there any correlation?

PURPOSE: The present research was conducted to evaluate the effect of the severity of dumping syndrome (DS) on weight loss outcomes after Roux-en-Y gastric bypass (RYGB) in patients with class III obesity. METHODS: The present retrospective cohort study used the dumping symptom rating scale (DSRS) to evaluate the severity of DS and its correlation with weight loss outcomes in 207 patients 1 year after their RYGB. The patients were assigned to group A with mild-to-moderate DS or group B with severe DS. RESULTS: The mean age of the patients was 42.18 ± 10.46 years and their mean preoperative BMI 42.74 ± 5.59 kg/m2. The total weight loss percentage (%TWL) in group B was insignificantly higher than that in group A, but besides that was not significantly different in the two groups. CONCLUSION: The present findings suggested insignificant relationships between the presence and severity of DS after RYGB and adequate postoperative weight loss.

Comparison of the Onset and End of Specific and Major Side Effects in Iranian Teenage Participants Vaccinated With COVID-19 Vaccine: Sinopharm and Soberana.

Background: Clinical trials were conducted on children on side effects after vaccination. We tried to assess the frequency and onset of the main symptoms in children who were vaccinated. We aimed to evaluate early and delayed adverse effects after coronavirus disease 2019 (COVID-19) vaccine among Iranian pediatrics and adolescents in a national survey. Methods: This cross-sectional study included people <18 years who received the Soberana (PastoCoVac) and Sinopharm vaccines since 2021. The basic information was gender, age, type of vaccine, and reaction after vaccination besides the main events that occurred for them. The required data were collected via a predetermined checklist by trained interviewers through phone calls by their parents or legal guardians. The independent t test and Fisher exact test were used. P values less than 0.05 were considered significant. Results: A total of 11,042 participants (age range, 10-18 years) consisting of 5374 boys (47.8%) and 5768 girls (52.2%) were studied and 88.1% of the children (n = 9727) were vaccinated by Sinopharm and 11.9% (n = 1315) by Soberana. The data of kidney-related side effects had delayed improvement of side effects after the Sinopharm compared with the Soberana vaccines (P = 0.012). Cardiovascular and hematological side effects showed early-onset (P = 0.006) and delayed improvement of side effects (P = 0.002) after the Soberana vaccine compared with the Sinopharm vaccine. Neurological side effects showed delayed improvement of side effects after the Soberana vaccine compared with the Sinopharm vaccine (P = 0.027). Joint-related side effects showed early-onset (P = 0.004) and delayed improvement of side effects (P = 0.023) after the Soberana vaccine compared with the Sinopharm vaccine. Respiratory side effects showed delayed improvement of side effects after the Soberana vaccine compared with the Sinopharm vaccine (P = 0.013), and dermatological side effects showed early-onset (P = 0.050) and delayed improvement of side effects (P = 0.035) after the Soberana vaccine compared with the Sinopharm vaccine. There was not any statistically significant difference regarding gastrointestinal side effects between the 2 vaccines (P > 0.05). Conclusion: The cardiovascular and hematological, joint-related (non-neurologic musculoskeletal) and dermatological side effects after the Soberana vaccine appear earlier and end later compared with the Sinopharm vaccine. Improvement of renal side effects in the Sinopharm vaccine group and improvement of neurological and respiratory side effects in the Soberana vaccine group occurred with delay compared with other vaccines.

Pediatric and adolescent COVID-19 vaccination side effects: A retrospective cohort study of the Iranian teenage group in 2021.

To determine the safety and efficacy profile of teenager COVID-19 vaccination. In this retrospective cohort study, contact numbers of parents of teenagers under 18 years of age referred to a teenager vaccination centers in Tehran-Iran to receive the corona vaccine were collected, and the following information was obtained via the phones: demographic information, type of vaccine, and the number of doses received, as well as additional information like complications and required treatments. Eleven thousand forty-two subjects aged 10-18 years, mean age 14.55 ± 1.83 year including 5374 boys and 5768 girls were investigated. 88.1% received the Sinopharm and 11.9% the Soberana vaccine. General side effects, including fatigue, fever and chills, injection site pain and dizziness, and so forth happened in 2978 cases; 7421 children presented with at least one general or organ-specific side effect following vaccination, including potentially critical side effects, such as vascular injuries, respiratory complication, and so forth. 0.1% of the subject needed hospital admission. The breakthrough infection happened in 200 individuals. Our study shows that Sinopharm and Soberana (PastoCoVac) COVID-19 vaccines are generally safe with no serious side effects in less than 18 years old. COVID-19 infection and reinfection can occur after vaccination, but the incidence is actually tolerable and significantly lower than in the unvaccinated group.

Husbands' participation in prenatal care and breastfeeding self-efficacy in Iranian women: A randomized clinical trial.

Background: Self-efficacy is an important psychological and motivational factor for continuation of exclusive breastfeeding. This study aimed to examine the effect of husband participation on self-efficacy of breastfeeding in postpartum period. Methods: This study was a single-blind clinical trial (IRCT2014012115163N2) conducted on 66 pregnant women who referred to health centers of Urmia in 2014. Convenience sampling method was used to select the participants and then they were randomly allocated to control and intervention groups using RANDBETWEEN function in Excel. Participants in the intervention group had 2 training sessions with 4-week interval. They could also use telephone counseling over study time. Those in the control group received the routine pregnancy care, and their breastfeeding self-efficacy was compared 1 month after delivery using Dennis Breastfeeding Self-Efficacy questionnaire. The data were analyzed using SPSS version 20. Chi square, independent and paired samples t test were used. Results: In this study, the mean score of breastfeeding self-efficacy in the intervention and control groups after intervention was 50.36±8.65 and 44.12±10.41, respectively, which showed a statistically significant difference (p=0.017). Conclusion: According to the results, one of the considerable strategies to enhance self-efficacy of breastfeeding is to involve husbands in prenatal care, which should be considered by the authorities and health professionals, including doctors, nurses, and midwives.

Remnant Gastrectomy and Gastric Bypass: A Systematic Review of Indications and Outcomes of Resectional Gastric Bypass.

BACKGROUND: In this systematic review, we aim to evaluate the reasons and outcomes behind remnant gastrectomy with or after gastric bypass procedures. RESULTS: A total of 66 studies examining 1918 patients were included in this study with 70% of female predominance. Twenty studies reported RGB on 1751 patients and 46 studies reported remnant gastrectomy after gastric bypass in 167 patients. The most common etiology of RGB was related to the in situ remnant stomach neoplasia in 10 studies on 981 patients; mostly for preventive intentions in high prevalence areas. Remnant gastrectomy after gastric bypass was performed to treat a complication such as GGF, retrograde bile reflux gastritis, cancer mostly adenocarcinoma. Studies revealed that RGB has similar weight loss in comparison to standard Roux-en-Y gastric bypass.

Comparing the safety and efficacy of sleeve gastrectomy versus Roux-en-Y gastric bypass in elderly (>60 years) with severe obesity: an umbrella systematic review and meta-analysis.

BACKGROUND: Today, bariatric surgeons face the challenge of treating older adults with class III obesity. The indications and outcomes of Roux-en-Y gastric bypass (RYGB) versus sleeve gastrectomy (SG) also constitute a controversy. METHODS: PubMed, Web of Science and Scopus were searched to retrieve systematic reviews/meta-analyses published by 1 March 2022. The selected articles were qualitatively evaluated using A Measurement Tool to Assess systematic Reviews (AMSTAR). RESULTS: An umbrella review included six meta-analyses retrieved from the literature. The risk of early-emerging and late-emerging complications decreased by 55% and 41% in the patients underwent SG than in those receiving RYGB, respectively. The chance of the remission of hypertension and obstructive sleep apnoea, respectively increased by 43% and 6%, but type-2 diabetes mellitus decreased by 4% in the patients underwent RYGB than in those receiving SG. RYGB also increased excess weight loss by 15.23% in the patients underwent RYGB than in those receiving SG. CONCLUSION: Lower levels of mortality and early-emerging and late-emerging complications were observed in the older adults undergoing SG than in those receiving RYGB, which was, however, more efficient in term of weight loss outcomes and recurrence of obesity-related diseases.

Safety and efficacy of Roux-en-Y gastric bypass as revisional bariatric surgery after failed anti-reflux surgery: a systematic review.

This systematic review evaluates the safety and efficacy of Roux-en-Y gastric bypass (RYGB) on weight loss and anti-reflux outcomes when used as a revisional bariatric surgical procedure after failed anti-reflux surgery. A systematic literature search next to the PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) guidelines was performed for articles published by 30 Mar 2022. After examining 416 papers, 23 studies were included (n = 874 patients). Primary anti-reflux surgery included mainly Nissen fundoplication (16 studies). Reasons for revisional surgery included predominantly gastroesophageal reflux disease (GERD) (reported by 18 studies), obesity (reported by 6 studies), and hiatal hernia (reported by 6 studies). Interval to surgical revision was 5.58 ± 2.46 years (range, 1.5-9.4 yr). Upper endoscopy at revision was performed for all patients; esophageal manometry and pH monitoring were reported in 6 and 4 studies, respectively. Mean body mass index (BMI) at revision was 37.56 ± 5.02 kg/m2 (range, 31.4-44 kg/m2). Mean excess weight loss was 69.74% reported by 12 studies. Delta BMI reported by 7 studies was 10.41 kg/m2. The rate of perioperative complications was 16.7%, including mostly stenosis, leakage, ventral hernia, and small bowel obstruction. Mean improvement rate of GERD was 92.62% with a mean follow-up of 25.64 ± 16.59 months reported in 20 studies. RYGB seems to be an efficient surgical treatment option in failed anti-reflux procedures, but should be performed in experienced centers for selected patients, since the rate of perioperative and long-term complications must be minimized. Cooperation between bariatric and reflux surgeons is essential to offer patients with obesity and GERD the best long-term outcome.

Management of leaks following one-anastomosis gastric bypass: an updated systematic review and meta-analysis of 44 318 patients.

INTRODUCTION: One-anastomosis gastric bypass (OAGB) complication, such as leakage, can be dangerous and should be managed properly, yet little data exist in the literature regarding the management of leaks after OAGB, and there are no guidelines to date. METHODS: The authors performed a systematic review and meta-analysis of the literature and 46 studies, examining 44 318 patients were included. RESULTS: There were 410 leaks reported in 44 318 patients of OAGB published in the literature, which represents a prevalence of 1% of leaks after OAGB. The surgical strategy was very variable among all the different studies; 62.1% of patients with leaks had to undergo another surgery due to the leak. The most commonly performed procedure was peritoneal washout and drainage (with or without T-tube placement) in 30.8% of patients, followed by conversion to Roux-en-Y gastric bypass in 9.6% of patients. Medical treatment with antibiotics, with or without total parenteral nutrition alone, was conducted in 13.6% of patients. Among the patients with the leak, the mortality rate related to the leak was 1.95%, and the mortality due to the leak in the population of OAGB was 0.02%. CONCLUSION: The management of leaks following OAGB requires a multidisciplinary approach. OAGB is a safe operation with a low leak risk rate, and the leaks can be managed successfully if detected in a timely fashion.

Cardiac fat pat change after laparoscopic sleeve gastrectomy and Roux-en-Y gastric bypass surgery: a systematic review and meta-analysis.

Cardiac fat pad is a metabolically active organ that plays a role in energy homeostasis and cardiovascular diseases and generates inflammatory cytokines. Many studies have shown remarkable associations between cardiac fat thickness and cardiovascular diseases, making it a valuable target for interventions. Our meta-analysis aimed to investigate the effects of the 2 most popular bariatric surgeries (sleeve gastrectomy [SG] and Roux-en-Y gastric bypass [RYGB]) in cardiac fat pad reduction. A systematic review of the literature was done by searching in Scopus, Web of Science, Cochrane, and PubMed for articles published by September 16, 2022. This review followed the meta-analysis rules based on the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) checklist. Nineteen studies met the inclusion criteria out of 128 potentially useful studies, including a total number of 822 patients. The results of subgroup analysis on the type of surgery showed that bariatric surgeries decreased the mean fat pad diameter, but the reduction was greater in SG than in RYGB. Epicardial and pericardial fat type showed a significant decrease of fat pad diameter. The results of subgroup analysis indicated RYGB had a significant reduction in mean fat pad volume. Computed tomography scan and cardiac magnetic resonance imaging showed a significant reduction of the mean cardiac fat pad volume. Epicardial and paracardial fat type showed a significant decrease in volume. The cardiac fat pad diameter and volume were significantly reduced after bariatric surgeries. SG showed greater reduction in fat pad diameter in comparison with RYGB, and RYGB had a significant reduction in mean fat pad volume.

Evaluation of the efficacy and safety of oral N-acetylcysteine in patients with COVID-19 receiving the routine antiviral and hydroxychloroquine protocol: A randomized controlled clinical trial.

BACKGROUND: The current absence of gold-standard or all-aspect favorable therapies for COVID-19 renders a focus on multipotential drugs proposed to prevent or treat this infection or ameliorate its signs and symptoms vitally important. The present well-designed randomized controlled trial (RCT) sought to evaluate the efficacy and safety of N-acetylcysteine (NAC) as adjuvant therapy for 60 hospitalized Iranian patients with COVID-19. METHODS: Two 30-person diets, comprising 15 single diets of Kaletra (lopinavir/ritonavir) + hydroxychloroquine (HCQ) with/without NAC (600 mg TDS) and atazanavir/ritonavir + HCQ with/without NAC (600 mg TDS), were administered in the study. RESULTS: At the end of the study, a further decrease in C-reactive protein was observed in the NAC group (P = 0.008), and no death occurred in the atazanavir/ritonavir + HCQ + NAC group, showing that the combination of these drugs may reduce mortality. The atazanavir/ritonavir + HCQ and atazanavir/ritonavir + NAC groups exhibited the highest O2 saturation at the end of the study and a significant rise in O2 saturation following intervention commencement, including NAC (P > 0.05). Accordingly, oral or intravenous NAC, if indicated, may enhance O2 saturation, blunt the inflammation trend (by reducing C-reactive protein), and lower mortality in hospitalized patients with COVID-19. CONCLUSION: The NAC could be more effective as prophylactic or adjuvant therapy in stable non-severe cases of COVID-19 with a particularly positive role in the augmentation of O2 saturation and faster reduction of the CRP level and inflammation or could be effective for better controlling of COVID-19 or its therapy-related side effects.

A systematic review and meta-analysis on GERD after OAGB: rate, treatments, and success.

INTRODUCTION: This review aims to investigate the gastroesophageal reflux disease (GERD) as one of the important concerns for both surgeons and patients after one anastomosis gastric bypass (OAGB). METHOD: PubMed, Scopus, Embase, Web of Science, and Cochrane were reviewed by the end of the 2021 with keywords relating to GERD, OAGB, and their equivalents. Data regarding OAGB, number of patients with GERD, treatment for GERD, endoscopy findings, the interval between GERD and OAGB were retrieved by two independent investigators. The primary effect/effect size measure was prevalence. RESULTS: 40 studies examining 17,299 patients were included revealing that 2% of patients experience GERD following OAGB. Reflux after revisional OAGB is six times higher than primary OAGB. Despite being unclear, medical and surgical treatments for GERD after OAGB were used in 60% and 41% of patients with estimated success rate of 85% and 100%, respectively. CONCLUSION: Based on how GERD was identified after OAGB, its rate ranged from 0 to 55%; the pooled rate of 2% is near to Roux-en-Y gastric bypass. GERD symptoms can be mild to be tolerated without medical treatment, moderate that respond to acid-reducing agents, or severe enough that are categorized as interactable and would need a surgical intervention.

Prophylactic Agents for Preventing Cardiotoxicity Induced Following Anticancer Agents: A Systematic Review and Meta-Analysis of Clinical Trials.

BACKGROUND: Anthracyclines can improve survival in many types of malignancies, but dose-dependent and irreversible results following the use of anthracyclines have been associated with cardiomyopathy. This meta-analysis aimed to compare the effects of prophylactic agents for preventing cardiotoxicity induced following anticancer agents. METHODS: In this meta-analysis, Scopus, Web of Science, and PubMed were surfed for articles published by December 30th, 2020. The keywords were angiotensin-converting enzyme inhibitor (ACEI), enalapril, captopril, angiotensin receptor blocker, beta blocker, metoprolol, bisoprolol, isoprolol, statin, valsartan, losartan, eplerenone, idarubicin, nebivolol, dihydromyricetin, ampelopsin, spironolactone, dexrazoxane, antioxidants, cardiotoxicity, n-acetyl-tryptamine, cancer, neoplasms, chemotherapy, anthracyclines, doxorubicin, daunorubicin, epirubicin, idarubicin, ejection fraction or a combination of them in the titles or abstracts. RESULTS: A total of 17 articles out of 728 studies examining 2,674 patients were included in this systematic review and meta-analysis. Ejection fraction (EF) values in the baseline, 6-month, and 12-month follow-up in the intervention group turned out to be 62.52 ± 2.48, 59.63 ± 4.85, and 59.42 ± 4.53, whereas in the control group appeared to be 62.81 ± 2.58, 57.69 ± 4.32, and 58.60 ± 4.58, respectively. Through comparison of the two groups, EF was found to increase in the intervention group by 0.40 after 6 months (Standardized mean difference (SMD): 0.40, 95% confidence interval (CI): 0.27, 0.54), thus proving higher than that of the control groups following the cardiac drugs. CONCLUSION: This meta-analysis showed that prophylactic treatment with cardio-protective drugs, including dexrazoxane, beta blocker, and ACEI drugs in patients undergoing chemotherapy with anthracycline, have a protective effect on LVEF and prevent EF drop.

International survey on complications of religious fasting after metabolic and bariatric surgery.

Religious fasting in Ramadan the 9th month of the lunar year is one of five pillars in Islam and is practiced for a full month every year. There may be risks with fasting in patients with a history of metabolic/bariatric surgery (MBS). There is little published evidence on the possible complications during fasting and needs stronger recommendations and guidance to minimize them. An international survey was sent to surgeons to study the types of complications occurring during religious fasting in patients with history of MBS to evaluate the risk factors to manage and prepare more evidence-based recommendations. In total, 21 centers from 11 countries participated in this survey and reported a total of 132 patients with complications occurring during religious fasting after MBS. The mean age of patients with complications was 36.65 ± 3.48 years and mean BMI was 43.12 ± 6.86 kg/m2. Mean timing of complication occurring during fasting after MBS was 14.18 months. The most common complications were upper GI (gastrointestinal) symptoms including [gastroesophageal reflux disease (GERD), abdominal pain, and dyspepsia], marginal ulcers and dumping syndrome in 24% (32/132), 8.3% (11/132) and 23% (31/132) patients respectively. Surgical management was necessary in 4.5% of patients presenting with complications (6/132) patients due to perforated marginal or peptic ulcer in Single Anastomosis Duodenoileostomy with Sleeve gastrectomy (SADI-S), one anastomosis gastric bypass (OAGB) and sleeve gastrectomy (SG), obstruction at Jejunojenostomy after Roux-en-Y gastric bypass (RYGB) (1/6) and acute cholecystitis (1/6). Patients after MBS should be advised about the risks while fasting including abdominal pain, dehydration, and peptic ulcer disease exacerbation, and a thorough review of their medications is warranted to minimize complications.

The effect of one bout submaximal endurance exercise on the innate and adaptive immune responses of hypertensive patients.

BACKGROUND: Changes in some of the immune system factors are associated with a risk of cardiovascular disease. Therefore, the purpose of this study was to investigate the effect of one-bout submaximal endurance exercise (OBSEE) on the innate and adaptive responses of hypertensive patients. METHODS: From among 70 men with hypertension, 20 men (mean age: 60.25±4.59 years, Body Mass Index [BMI]: 29.57±3.68 kg/m2, and the maximal oxygen uptake [VO2max] 34.83±2.11 mL/kg/min) were chosen. The statistical sample performed OBSEE for 30 minutes and at 60-65% of the maximum heart rate reserve (MHRR). Blood sampling was performed to measure the response of immunoglobulin A (IgA), immunoglobulin G (IgG), immunoglobulin M (IgM), white blood cells (WBCs), neutrophil (NEUT), basophil (BASO), eosinophil (EO), monocyte (MONO) and lymphocyte (LYMPH) of hypertensive patients before and immediately after exercise. Plasma volume changes (PVCs) were also calculated in order to find out accurate effectiveness of exercise. Shapiro-Wilk test was used to normalize the research data. To analyze the data, paired sample t-test was used at significant level (P≤0.05). The hypothesis test was performed using SPSS software v. 19. RESULTS: The results after adjusting for PVCs showed that OBSEE significantly increased WBCs (P=0.001) in hypertensive patients. On the other hand, a significant decrease was observed in EO (P=0.001) and MONO (P=0.001) levels after OBSEE. Significant changes were not found in NEUT (P=0.072), BASO (P=0.106), LYMPH (P=0.440), IgA (P=0.382), IgG (P=0.245) and IgM (P=0.081) levels. CONCLUSIONS: It seems that OBSEE can reduce the risk of hypertension caused by elevated EO and MONO in hypertensive patients.

Safety and Efficacy of One Anastomosis Gastric Bypass on Patients with Severe Obesity Aged 65 Years and Above.

PURPOSE: With the global increase in life expectancy and the subsequent impaired quality of life in older obese adults, modalities such as bariatric surgery become crucial to help lose excess weight. This study was conducted to evaluate the effectiveness and safety of one anastomosis gastric bypass (OAGB) in patients 65 years old and above. MATERIALS AND METHODS: This retrospective cohort study was conducted on 61 patients with severe obesity aged ≥ 65 years through Iran National Obesity Surgery Database. The patients had undergone OAGB and were followed up for 12 to 60 months. The required data was extracted through national database. RESULTS: Mean age and BMI of the patients were 67.62 ± 2.03 years and 46.42 ± 5.46 kg/m2, respectively. Regarding gender, 90.1% of the participants were female. Mean operative time and length of hospital stay were 41.37 ± 13.91 min and 1.16 ± 0.61 days, respectively. Five patients (8.19%) required ICU admission. The changes in %TWL after 3, 6, 12, 24, 36, 48, and 60 month follow-up was 18.62%, 25.51%, 32.84%, 35.86%, 38.49%, 31.41%, and 29.52%, respectively. The resolution of gastroesophageal reflux disease, diabetes mellitus, dyslipidemia, obstructive sleep apnea, and hypertension after 24 month was about 100%, 65%, 73.33%, 100%, and 76%, respectively. The postoperative early and late complications were 6.53% and 11.46%, respectively. We did not find significant difference in above results between two age groups of 65-70 and > 70 years. CONCLUSIONS: OAGB can be a good choice in older obese adults because of its shorter operative time, higher potency, and low complication rate.

One anastomosis gastric bypass as a one-stage bariatric surgical procedure in patients with BMI ≥ 50 kg/m2.

In patients with BMI ≥ 50 kg/m2, it is difficult to select an appropriate procedure that can lead to optimum results. This study aims to evaluate mid-term weight loss outcomes in patients with BMI ≥ 50 kg/m2 following one anastomosis gastric bypass (OAGB) as a one-stage procedure. A prospective study was conducted on patients with BMI ≥ 50 kg/m2, aged 18 years and above who had undergone primary OAGB from January 2016 to February 2019 with at least two years follow-ups. A total of 197 patients with BMI ≥ 50 kg/m2 had underwent OAGB. The mean age was 38 years and the mean pre-operative BMI was 53.7 kg/m2. Mean EWL% were 63.7%, 67.8% and 66.2% at one, two and five years after OAGB respectively. The highest level of EWL% was 68.4%, which was achieved in the 18th month following OAGB. OAGB can be performed safely in patients with BMI ≥ 50 kg/m2 as a one-stage procedure with acceptable weight loss outcomes and remission of obesity associated medical problems.
